Thanks for posting this information. I see "Proof of Brain" a lot on Steemit and Hive, but I am not sure exactly what it is. When I look it up, PoB looks like a generic term for getting rewards for posting and commenting on content. However it seems that there is another definition of PoB, where it refers to a specific community or "tribe" of users. I feel that this article deals with the latter definition, but I'm still not clear on exactly what that means. Do you have your own token that you get rewarded with, in addition to Steem/SBD or Hive/HBD or Blurt?
